摘要: A similarity solution is derived for the two-dimensional propagation of a liquid-filled crack. This includes both flow problem within crack and fracture through stress intensity factor. The results are applied to emplacement dikes sills migration magma lithosphere. We show that these applications limited by viscosity magma; resistance elastic medium can be neglected. Limitations on due solidification during also considered. As typical example dike or sill, we conclude with 102 Pa s injected into length 2 km width 0.5 m in period 15 min; velocity about s−1. propagating, viable mechanism
